What is Tinnitus: The Characteristics
Tinnitus can be perceived in one or both ears or in the head. It is usually described as a ringing noise, but in some patients it takes the form of a high pitched whining, electric, buzzing, hissing, screaming, humming, tingling or whistling sound, or as ticking, clicking, roaring, "crickets" or "tree frogs" or "locusts (cicadas)", tunes, songs, beeping, or even a pure steady tone like heard in a hearing test. It has also been described as a "whooshing" sound, as of wind or waves. Tinnitus can be intermittent or it can be continuous in which case it can be the cause of great distress. In some individuals, the intensity of tinnitus can be changed by shoulder, head, tongue, jaw, or eye movements
Most people with tinnitus have hearing loss, in that they are often unable to properly hear external sounds which occur within the same range of frequencies as their "phantom sounds." This has led to the suggestion that one cause of tinnitus might be a homeostatic response of central dorsal cochlear nucleus auditory neurons that makes them hyperactive in compensation to auditory input loss. The sound perceived may range from a quiet background noise to one that can be heard even over loud external sounds. The term "tinnitus" usually refers to more severe cases. Heller and Bergman (1953) conducted a study of 100 tinnitus-free university students placed in an anechoic chamber and found that 93% reported hearing a buzzing, pulsing or whistling sound. Cohort studies have demonstrated that damage to hearing (among other health effects) from unnatural levels of noise exposure is very widespread in industrialized countries.
